🐛 Depositing PalletAttributeSet on incorrect nft (paritytech#2740)

## Context

Implementing `HolderOf(collection_id)` we have observed a fancy glitch
where pallet deposits event with incorrect values

### Test case 

[Observe following
extrinsic](https://assethub-polkadot.subscan.io/extrinsic/0xdc72321b7674aa209c2f194ed49bd6bd12708af103f98b5b9196e0132dcba777)

To mint in collection `51` user needs to be `HolderOf(50)`.
Therefore current user is owner of item `394` `witness_data {
owned_item: 394 }`

All checking is done correctly, storage is updated correctly

However the event which is emitted does not make semantic sense as we
updated storage for `50-394` not for `51-114`

## The fix 

This PR fixes that depositing `PalletAttributeSet` emits correct values.
